Excellent discussion - re-answered a question I've been curious about for years that is now cropping up get again with a bunch of new clients.
My original search query on this topic included the word "synergy" and it is interesting that this link points to excellent useful discussions and various other experts (Greg Jarboe / ICrossing) discussions that are all about "symbiosis" between organic and AdWords traffic.
I guess it pays to Google on synonyms!
Love to get eWhisper and various other AdWords WebmasterWorld admins and senior members in on this topic!
